RAM: 128 MiB
Flash: 16 MiB NOR (Macronix mx25l12805d)

Wireless: MT7915E (2.4G) 802.11ax/b/g/n MT7915E (5G) 802.11ac/ax/n
Ethernet: 2 x 1Gbs
Button: 1 x "Reset" button

Power: PoE

Manufacturer Page:
http://en.comfast.com.cn/index.php?m=content&c=index&a=show&catid=84&id=75

Flash Layout:
0x000000000000-0x000000030000 : "bootloader"
0x000000030000-0x000000040000 : "config"
0x000000050000-0x000000060000 : "factory"
0x000000090000-0x000001000000 : "firmware"

First install:
1. Set device into http firmware fail safe upload mode by pressing the reset button for 10 seconds while powering
   it on. Once the LED stops flashing, safe mode will be running.
2. Set PC IP address to 192.168.1.2
3. Browse to 192.168.1.1 and upload the factory image using the web interface.
